What to do when your PayPal is not syncing anymore? If I disconnect and reconnect will it mess up what transactions had previously synced and create duplicates?

Let's get your Paypal up and running, ursulanakeda.

First, manually update your account. Here's how:

1. Click Banking, then go to the Banking tab.
2. Click the Update button.

Then, if you've encountered a specific error message, you can refer to this article for the troubleshooting steps: Common Online Banking Error Codes for Downloaded Transactions (Bank Feeds).

Additionally, using a different browser can help fix issues like this (Internet Explorer, Google Chrome, or Mozilla Firefox).

We don't recommend disconnecting and reconnecting the account. It will re-download the transactions and will create duplicates. 

Get back to me if you need further help. I'm just a comment away.
